Question

由于Killed: 9错误，配置脚本的摘录形式失败，即iOS 5只能运行已签名应用。所以我需要找到一种方法将ldid -s放在这些测试中的某些位置，只有问题在哪里。

任何???

失败

最后是./configure脚本..

我不得不承认，除了最简单的shell脚本之外，我的阅读能力都很差，但基本上，你需要在运行它之前伪造可执行文件。您想要运行的可执行文件看起来像conftest，对吧？所以，试着在这个块中签名：

if { { eval echo "\"\$as_me\":${as_lineno-$LINENO}: \"$gmp_compile\""; } >&5
  (eval $gmp_compile) 2>&5
  ac_status=$?
  $as_echo "$as_me:${as_lineno-$LINENO}: \$? = $ac_status" >&5
  test $ac_status = 0; }; then

  #begin added code
  ldid -S ./conftest
  #end added code

  if (./a.out || ./b.out || ./a.exe || ./a_out.exe || ./conftest) >&5 2>&1; then
    cc_for_build_works=yes
  fi
fi

显然，如果现有ldid中找不到/usr/bin/ldid，则可能需要提供PATH的完整路径（例如a.out）。

更新：下面每张海报的评论，conftest实际上是需要签名的可执行文件，而不是{{1}}。

配置脚本和ldid
